® This manual contains the information you need to install the BACnet Communication Module on a MicroTech III Chiller Unit Controller, incorporate it into the BACnet network, and maintain it. Hazard Identification Messages DANGER Dangers indicate a hazardous situation that will result in death or serious injury if not avoided.
The BACnet Communication Module is a printed circuit board with a plastic enclosure that connects to the left side of the McQuay D-Net™ Module as shown in Figure 1 or directly to the unit controller. The BACnet Communication Module provides access to the unit controller variables and parameters via BACnet.
Red flashing with 2Hz = Software error. Hardware error. In the event that this should occur, cycle power to the unit controller to attempt to clear the problem. Contact the McQuay Controls Customer Support Group at 866-4MCQUAY (866-462-7829) for additional assistance if necessary.
BUS LEDs The BUS LED indicates the communication status between the BACnet Communication Module and the BACnet IP network. The table below describes the status of the BUS LED. BUS LED Color Meaning Green The unit controller is capable of communicating to the network. The unit controller is not capable of communicating to the network.
Installation The following section describes how to field install a new BACnet Communication Module or replace an existing BACnet Communication Module on the MicroTech III Chiller Unit Controller so that it can be incorporated into the BACnet network. CAUTION Electrostatic discharge hazard. Can cause equipment damage.
Electric shock hazard. Can cause personal injury or equipment damage. This equipment must be properly grounded. Only personnel knowledgeable in the operation of the equipment being controlled must perform connections and service to the MicroTech III Chiller Unit Controller. 1. Remove power from the unit controller.
Integration Once the BACnet Communication Module has been properly installed on the MicroTech III Chiller Unit Controller, it is then necessary to configure the unit controller for integration into a Building Automation System (BAS) via the BACnet IP network. The configuration process is described in the following section.
This procedure may take a minute while the BACnet Communication Module powers up. Note: The Actual IP Address displays 0.0.0.0 if the network cable is not attached. Figure 6.
